Step 3. Select Organization
At the Organization step of the wizard, select a Salesforce organization whose records you want to restore from the Restore from drop-down list. For a Salesforce organization to be displayed in the list, it must belong to the company specified at step 1.
By default, the records are restored to the same Salesforce organization. However, you can choose to restore records to another organization, for example, if you want to populate (seed) a sandbox with backed-up data of your production or another Salesforce sandbox organization. To do that, select a Salesforce organization to which you want to restore the records from the Restore to drop-down list. For a Salesforce organization to be displayed in the list of available organizations, it must belong to the company specified at step 1 and be compatible with the organization whose records you want to restore. This means that you can restore from a production or sandbox organization only to its sandbox copies.
When you restore to another organization, make sure that metadata of the object that you want to restore match metadata of the object in the target organization. If metadata is missing or does not match, you must first create a dedicated metadata restore job.
